Abstract
In order to breed hemp variety with nondrug type adapted to Korea, a total of 44 accessions were introduced from Center for plant breeding and reproduction research (CPRO) In Netherland and evaluated for plant growth characteristics and contents of cannabinoids such as tetrahydrocannbinol (THC), cannabidiol (CBD), Cannabinol (CBN) in Korean climatical and geographical condition. 1. In Korean geographical position which latitude is $34^{\circ}N$, days to flowering and stem length were shorter than in Netherlands which latitude is $52^{\circ}N$. But THC content was not shown significant difference between two areas. 2. Corrected accessions of hemp were classified into 3 variety groups by cluster analysis and 4 accessions including Korean local variety were not classified into any variety group. 3. Most hemp accessions have low THC contents but were not suitable for fiber production in Korea due to short days to flowering and stem length. 4. Among the introduced accessions, IH3 was suitable for breeding material of fiber hemp with non-drug type because of low THC content and similar days to flowering with Korean local variety.
